This Week's Stupid Customer

Instead of bitching about work, which I could do forever to everyone's boredom, I'm gonna post once per week describing one encounter over the counter with an idiot. Since management loves telling us employees are 'customers' too, my fellow 'partners' as they're called at NAME OF COMPANY will be subject to these posts as well.
Having said that I can't actually think of an encounter with a stupid customer so far this week. Oh well.
